Applic'ation filed June "I, 1907. Serial No. 377,686.

To all whom "it may concern.

Be it known. that. I, Put Wow); .iittt'iii, it citizen of the tinit d Stanresiding at the oily o'l Chicago, in the county nit Cool; and lStntc of Illinois, have inxwrnted u curtain now and llfiti lll (.irvcr 'l'or (,tmtrolling Devices o1" .\I0t.-h .-inirnl Mush-til lnstrurnmitsv of which the iollor. ing is n spociiit-utitm, ltiftltl'ltfi. ht in'g hnd llilt'tllt to tho inst-ompinning drnwlugs.

My invention compristj-s invans for iiltvrnutoly conrroaling and tnxposing tho in-rinunlly opornhlt: devicns tor (I-ontrollin in: tvinpo, oxuression and Olllttl. int-clntnisnis oi st ll pluy mg mus-aired instruments andv has for two print-ipal l)j(tjt5, first, when in 'rlosod position, to provide it nuut and suitable cover for the above llltll ll lllttl. dt -vit'r-s; and sort-ind, wht-n open, to oxposu :nid 'nllnw t1"(l'-l$ to them for mnnipuhttion rind. providti :i substantt-ial and convenient support for tho wrists of tho operator.

Another object of my vido means through whit-h the support invention is to prolot the wrists will ho rt-ntdt-rvd :uljustnhlr in any desired (.ltigrct: of forward motion withoutin tiny rnannor sacrificing strength or solidity. l have shown tho dvvivu in the drawings as applied to n iia-no which is providnd with the utstiztl keys or nuinunl pinging and also with interior 21Ht ITlfltlC-PlttlYlllg niochnnisin; wherein Figure l is n sectional 2nd. view ot the forward 0nd of a. .iuno liP-X-idtlllt, shunting the device in closet position and noting therein as a. cover for the lingerrip of 0110 of a possibleseries of controlling (wars; and. Fig. 2 is n VlOW similar to Fig. 1, showing; the dot-"ion. in. open position and acting tlttntl'll us it rostl'or the l'iands or wrists. Fig. 3 is it pvrspotztivc view of the device in extended or open posi 5 tion, SllUWlIh the cmivonit-int lomtlon ol' the rest supplied? for tho wrists of tho opvrntor during manipulation of tho t-xposvd 'Iingvr gr] is.

".hz': interi r construction of t'nvsv instruments is so well known that. dvsrription may he stillicient to say that the automatic. int-.nlnniisin therein contained, is under the control of tho operator by ninnns of n Stl'lPH oi r'ontrollinglevers whi husuiilly (\xtvnd to a. position mnvenicnt for nninipuhition at the 'lorwnrd vdp'o of the key-tnhlv and. are providvd with up- (As shown at 5).

t Instruments of this class are usually provided with openings in the. upper and lower fronthostrds or panels, through which access may he. had toothor parts concerned in tho automatic opuration, and these 0 onings are ndnptod to be closedv t0 concert such parts when notin service. In pursuance of this o'njtwrt .t'or concealment of parts identified with tho :tntoi'nutit; )l:iying-rnechnnism, I have provided it no'vul and simple iCVlQC for concealing the. otherwise exposed ends of tho controlling-luv 1 represents the. tuhln, 2 the hwy-slip or lork-rnil, 3 the piano keys, 4 the forward kt-y-rnil, and ,3 the hintdles or lingcwgrips at the i'orwnrdent-ls of tho controlling-lotiers.

In my pl'flltl'l't'il 'lUllll oi construt-t-ion, tho koy-slip l nds at it point upon hitch sid'o-ol' tho rontrolling-lovers 5 which project forwardly into the space thus tLllUWttl, and I have provided a C(JVtt for tht-tn in the shape oi ninovnhlo soc-Lion 6. This sanction is 1'1!- r-vsst-d upon the innur side and when closed arts as n t-ontinuntion of tho. key-slip 2.

At the point l rigidly nttnr'h' tho horizontal guide :tl'ltl support lJtLlS S by rivrtinp; tho upturned ends thoruoi to n suhstnntinl tho innor surface of tho recess.

I provide in tho luay-taililc l, two grooves or cl'innnuls 7 which (*Xttilltl rvnrwnrdly from a .point lot-ntcd fttt enough forward of the face of the key'rnil 4 to allow admission and witljidrnwal of the two support-burs 8.

\Nhvn the cover 6 is closvd, tho 'l'orwz'trd. (nds oi" tho su 7 )(H'ES 8 rest upon the surl'i cn of tho koy-tnilv l. and cxtt-nd marwnrdly undt-r thev keys for n oonsidernhlc distnnoo lioforo bending sluir )ly (.lownwnrd into and i continuing in tho (:iosoly fitting groovt's 7. When, howuvttr, tho cover 6 drawn into open position, tho operation will cause the support to slide. horizontally forward in tho grooves 7 until tho bends 10 in the said sup ports stop against tho forward ends of t e l roovus. 'lho support-hurs '8 are 01" substinitial thicluivss and the grooves 7 are out t-ssary that whilo tlust: tilnn'ips allow iron lengthwise inovomoi'tt ui uthc supports in the (Fig, l) ooniplutvly conceals the lovers and plzttu, which is in turn svctnrnly screwed to suiliciontly dot-p to allow the roar portion of conventional piano kc rsupports as the bearing surfaces are always -m contact.

I am aware that many modifications of this invention may be devised by those skilled in the art and I do not wish to limit myself to the exact construction herein demonstrated, but

What I do claim and desire Letters Patent is:

1. In a musical instrument, the combination of a key-table, keys above said table, a rail above said table and near the forward end of said ke s and means attached to said rail and movalily supported by said table to su port said rail for horizontal movement.

s. In a musical instrument, the combination of a key-table, a key-slip section and means attached to said section and slidably supported by said key-table to support, said section for horizontal movement.

3. In a mechanical musical instrument, the combination of controlling devices and a cover mounted for horizontal movement rearwardly toward said devices to conceal to secure by them and forwardly from said devices to ex-' pose them.

'4. In a mechanical musical instrument, I

the combination of controllingdevices, a table, a hand-rest, and means rigidly secured to said hand-rest and slidably supported by said table to support said hand-rest for 11011- zontal movement into and from close proximity to said controlling-devices.

5. Ina mechanical musical instrument,

6. In a mechanical musical instrument,

the combination with, a key-table, controlling devices and a rest adapted to be moved toward and from said devices, of recesses within said key-table andsupporting means attached to said rest and acting within said recesses to movably supp or t said rest for the purposes described. v I

7. In a layer piano, the combination with the key sip having a cut away portion of the extpression or action levers in the space forme by said cut away portion, a cover casing having sliding movement and designed to fit the cut away poiition when closed, and a support therefor designed to allow .the

cover casing being withdrawn.to-uncover the expression evers as and for the purpose specified. Signed at Chicago, nmt two subscribing witnesses.
